Kokubyaku no Avesta

Under the world of the first Divine Throne, two forces are killing each other relentlessly. Black and White, Light and Darkness, Good and Evil. Until the other is destroyed, the fighting will never stop. That is the instinct called Avesta.

Following the wicked warrior Magsarion and his path of remorseless breaking dualism, along with Quinn, who is tasked with collecting a "miracle".
